Sleep tracking is an important feature of many wearable health-tracking devices. Garmin's Vivofit is one such device that can monitor your sleep by tracking your motion and heart rate. To enable Sleep Mode on the VivoFit, you must press and hold the device key, releasing it when the watch displays SLEEP. The VivoFit 4, for example, has been used in clinical settings to assess sleep in youth experiencing sleep disturbances. While automatic sleep tracking is generally preferred, some Garmin watches allow users to trigger Sleep Mode manually. This can be done by navigating to the Sleep widget on the watch face and tapping the moon icon. Once the tracker syncs with your account, you can view your sleep stats by clicking on Stats under the Home menu and scrolling down to SLEEP.

What You'll Learn

Enabling Sleep Mode on the VivoFit
To enable Sleep Mode on the VivoFit, press and hold the device key. The device will cycle through several modes. Release the device key when the watch displays "SLEEP". To exit sleep mode, press and hold the device key again. This will return the watch to its normal display.
Once your VivoFit tracker syncs with your account, you will be able to view your sleep stats by clicking on "Stats" under the Home menu and scrolling down to the "SLEEP" section.
While most modern Garmin watches use Advanced Sleep Monitoring to track sleep stages and body battery recovery automatically, some watches allow you to trigger sleep tracking manually. To do this, navigate to the Sleep widget by scrolling down from the main watch face.
Garmin watches use optical HRM, HRV, and the accelerometer to determine sleep stages, including light sleep, deep sleep, and REM sleep. The accelerometer sensor in the Garmin Vivofit 4, for example, can be used to assess sleep in individuals with sleep disturbances. However, it is important to note that the validity of sleep tracking may vary depending on the monitor and population.

Viewing sleep stats
To view your sleep stats on your VivoFit device, you must first ensure that your tracker has synced with your account. Once this is done, you can view your sleep data by accessing the Home menu, clicking on "Stats", and scrolling down to the "SLEEP" section.
The VivoFit 4 is an entry-level monitor that does not collect photoplethysmography or heart rate data. Instead, it uses an accelerometer sensor to determine when you are in light sleep, deep sleep, or REM sleep. It predicts sleep onset and offset times, total sleep time, sleep onset latency, and wake after sleep onset.
The VivoFit 5, on the other hand, provides more detailed sleep tracking. It can show you how much light sleep, REM sleep, and deep sleep you get per night. It also takes into account the amount of time spent awake and any sleep disruptions to give you an overall sleep score.
To enable Sleep Mode on the VivoFit, press and hold the device key until the watch displays "SLEEP". Press and hold the device key again to exit Sleep Mode and return to the normal display.
You can also view your sleep stats on your phone by installing the Sleep as Android app and connecting your Garmin device. This allows you to see graphs of your movement during sleep and access other features such as gentle vibrations for a natural wake-up.

Adjusting sleep settings
To adjust the sleep settings on your VivoFit, you must first enable Sleep Mode. To do this, press and hold the device key until you cycle through several modes, then release the key when the watch displays "SLEEP". You can exit Sleep Mode by pressing and holding the device key again. Once Sleep Mode is enabled, you can adjust your sleep settings by navigating to Settings > User Settings. Here, you can ensure that your personal information, such as age and weight, is correct as this will affect the device's estimates about your sleep quality.
While Garmin watches track sleep automatically by default, you may want to adjust your sleep settings to get the best possible experience. For example, you can manually add sleep time to a particular day in Garmin Connect: open the More menu, tap Health Stats > Sleep, navigate to the day in question, and select Add Sleep Data. This will give you a flat hour total with no estimated time spent in certain sleep stages.
Some Garmin watches also let you trigger Sleep Mode manually from the sleep widget. To do this, scroll down from the main watch face to the Sleep widget. Additionally, you can enable Heart Rate Monitoring in Settings > Sleep Tracking > Wearables. This will allow you to view your heart rate data during sleep.
If you are using a Sleep as Android app, you can initiate the connection between your watch and phone by launching the Sleep app on the watch. However, Garmin designed it so that it is not possible to programmatically launch an app on the watch without asking the user for consent. This is because all ConnectIQ apps are treated as "activities," and the watches only allow one app to run at a time.

Manually adding sleep time
To manually add sleep time to your Vivofit device, you must first open the Garmin Connect application on your phone. Then, follow these steps:
- Tap the three-dash icon or "More" in the bottom menu.
- Go to "Settings" and then "User Settings".
- Ensure that your personal information, such as age and weight, is correct, as this will affect the device's sleep quality estimates.
- Adjust your typical bedtime and wake-up times to set when your watch goes into sleep mode by default.
- Open the "More" menu and tap "Health Stats".
- Select "Sleep" and navigate to the day in question.
- Select "Add Sleep Data" to manually add sleep time to that particular day.
Note that this method will only provide a flat hour total without an estimated time spent in different sleep stages.

Using Sleep as Android
To use Sleep as Android with your Vivofit, you must first install the Sleep as Android companion app on your phone. Once the app is installed, you can enable the connection in Settings > Wearables > Use Wearable > Wear OS. Test the connection in Settings > Wearables > Test Sensor. You should see a graph reacting to your movement.
Next, install the current version of the watch app through the ConnectIQ Store (Connect IQ 3.1 and higher). Make sure that all the apps are installed, then select Sleep > Settings > Sleep Tracking > Wearables > Use Wearables > Garmin. For HR data, enable Heart Rate Monitoring in Settings > Sleep Tracking > Wearables. To start sleep tracking with your watch, tap "Start Tracking" on the Homescreen.
If you are having issues with muted vibrations for lucid cues or anti-snoring alerts, go to Settings > System > Sleep Mode on your wearable and disable Do Not Disturb while sleeping. Make sure Status Notification and Allow Vibrations are enabled on the wearable in Settings > Smart Notification > Notifications > Overall Usage and Apps > Apps.
Finally, make sure that you are not accidentally starting the Sleep as Android app from your watch, as this will start sleep tracking immediately. You can disable this in Settings > Sleep Tracking > Automatic Sleep Tracking > Start Sleep Tracking.
